Abstract
Description
前記一対のシート1,2の前記第1面1f,2fの間に配置され、かつ、互いに離間して配置された複数の弾性部材Fと、
前記一対のシート1,2の第1面1f,2fにおいて前記一対のシート1,2が接着剤を介することなく互いに溶着構造で接合され、かつ、前記弾性部材Fを保持し、前記弾性部材Fの伸縮方向Dfに交差する方向Dpに延び、前記隣り合う弾性部材F間において前記伸縮方向Dfに互いに離間した複数の接合部3と、
前記弾性部材Fが収縮している状態において前記複数の接合部3の間に現れる複数の襞Pとを備え、前記各接合部3は、
前記各弾性部材Fの前記交差する方向Dpの両側に配置された複数の強接合部3sと、
前記各弾性部材Fのうち互いに隣り合う弾性部材Fの間において、かつ、前記複数の強接合部3sのうち互いに隣り合う強接合部3sの間に配置された弱接合部3wとを包含し、前記弱接合部3wにおける前記一対のシート1,2同士の接合強度は前記強接合部3sにおける前記一対のシート1,2同士の接合強度よりも小さい。
また、弱接合部はシートの溶融が抑制される。そのため、伸縮シートが柔らかくなる。
前記アンビルロール50と協働して前記一対のシート1,2を互いに溶着すると共に前記一対のシートで前記弾性部材Fを保持させる溶着装置70とを備え、
前記アンビルロール50は、前記アンビルロール50の外周面51に形成され前記アンビルロール50の幅方向Sに延びる突条52を複数備え、
前記各突条52は前記強接合部3sを生成するための複数の高突条部52Hと、前記弱接合部3wを生成するための複数の低突条部52Lとを包含し、
前記高突条部52Hおよび低突条部52Lは前記幅方向Sに間欠的に設けられ、
前記低突条部52Lの高さH1は高突条部52Hの高さH2よりも低い。
一方、前記圧力の高い高突条部では一対のシートが互いに確実に溶着される。したがって、弾性部材Fを高接合部において安定して保持し得る。
前記肌面および/または非肌面において前記襞Pが突出している。
前記搬送溝Gは前記幅方向Sの両側の前記高突条部52Hで定義されている。
まず、弾性部材Fが伸張した状態について説明する。
図4Aの製造装置はアンビルロール50、導入装置60および溶着装置70などを備える。
本実施例では、接合部3は複数の第1接合部31と第2接合部32とを備える。前記各第1接合部31は前記弾性部材Fの伸縮方向Dfに交差する第1方向D1に延びる。複数の第2接合部32は前記伸縮方向Dfおよび第1方向D1に交差する第2方向D2に延びる。
また、図10Cに示すように、各接合部3は不連続であってもよい。
たとえば、伸縮シートは着用物品以外の製品に適用されてもよい。
また、前記実施例1では前記強接合部3sの長さLsよりも前記弱接合部3wの長さLwの方が大きい場合について説明した。これに代えて本発明の伸縮シートは、弱接合部の長さが強接合部の長さと同じ場合であってもよく、あるいは強接合部の長さよりも小さい場合であってもよい。いずれの場合も弱接合部が破断され難いので、接合部が連続して長く破断することが防止される。
したがって、そのような変更および修正は、請求の範囲から定まる本発明の範囲内のものと解釈される。
